Definitions

  • the present invention relates to a showcase equipped with a price rail for holding display devices or price cards for showing product names, prices, etc.
  • the showcase is provided with a display devices or price cards for displaying product names, prices, etc., a price rail that is disposed along a front edge of a shelf and has a locking portion formed on a front surface thereof to hold the lower ends of the display devices or the price cards, and a guard that is disposed in the gap between the price rail and the shelf and has its upper end positioned above the upper end of the price rail.
  • the guard has a retaining portion for retaining the upper ends of the display devices or the price cards.
  • the display devices or the price cards of the conventional example mentioned above has been posing a problem in that the majority of the display portions of the display devices or the price cards is exposed, so that they are easily soiled by dust or the like, and if the display devices or the price cards are made of, for example, paper or the like, then they deteriorate and become unusable soon.
  • the display devices or the price cards do not transmit light therethrough on shelves made of steel plates, preventing fluorescent lamps located thereunder from directly illuminating products rested on the shelves from below. Therefore, the illumination for the products cannot be improved, adversely affecting the promotion of customers' appetite for buying.
  • the present invention has been made with a view toward solving the technological problems with the prior art described above, and it is an object of the present invention to provide a showcase that allows prolonged use of price cards even if they are made of, for example, paper or the like, by protecting display devices or price cards from being soiled by dust or the like, by preventing the display devices or the price cards from being lost, and that also prevents products from falling off a shelf, and improves the illuminance on products by a plane fluorescent lamp provided on a shelf to promote customers' appetite for buying, thereby contributing to increased sales.
  • a showcase including a shelf for resting products thereon in a stock compartment, a riser flange being provided at a front portion of the shelf to restrict the products from moving forward, and a price rail being installed on the riser flange, wherein the price rail integrally includes a locking portion locked onto the riser flange, an insertion portion which is provided at the front of the locking portion and in which a price card is inserted, and an abutting portion which is provided above the insertion portion and restricts the product from moving at above the riser flange.
  • the chance of a price card being soiled by dust or the like is minimized, so that a price card made of, for example, paper or the like can be used for a longer period of time. Furthermore, since the price card is inserted in the insertion portion, the chance of the price card coming off and being lost can be also minimized.
  • the abutting portion that abuts against products is higher than the riser flange of the shelf, making it possible to prevent products from falling off the shelf.
  • a showcase including a shelf for resting products thereon in a stock compartment, a riser flange being provided at a front portion of the shelf to restrict the products from moving forward, and a price rail being installed on the riser flange, wherein the price rail is integrally formed of a locking portion locked onto the riser flange, an insertion portion which is provided at the front of the locking portion and in which a price card is inserted, and an abutting portion which is provided above the insertion portion and restricts the products from moving at above the riser flange, and a plane fluorescent lamp is provided at the front of the shelf.
  • the plane fluorescent lamp irradiates areas above and below itself at the same time, so that the illuminance of products rested on the shelf provided with the plane fluorescent lamp and the illuminance of products rested on a shelf under the above shelf can be both improved.
  • This promotes customers' appetite for buying the products, enabling contribution to increased sales.
  • the plane fluorescent lamp is thin and requires a small installation space, hardly causing a reduction in the quantity of products that can be rested on the shelf.
  • the plane fluorescent lamp features good low-temperature properties, permitting a solution to a problem in that the illuminance drops due to temperature.
  • price cards are hardly soiled by dust or the like, so that even if the price cards are made of, for example, paper or the like, they can be used for a prolonged period of time and are hardly lost.
  • the abutting portion that abuts against products is taller than the riser flange of the shelf, making it possible to prevent products from falling off the shelf.
  • a showcase including a shelf formed of a transparent or translucent resin for resting products thereon, the shelf being provided in a stock compartment, a riser flange provided at the front of the shelf to restrict the products from moving forward, and a price rail installed on the riser flange, wherein the price rail is integrally formed of a locking portion locked onto the riser flange, an insertion portion which is provided at the front of the locking portion and in which a price card is inserted, and an abutting portion which is provided above the insertion portion and restricts the products from moving at the rear of the riser flange, and a plane fluorescent lamp is provided at the front bottom of the shelf.
  • the shelf is formed of a transparent or translucent resin
  • the light irradiated upward from the plane fluorescent lamp positioned at the front bottom of the shelf illuminates the front surface side of the products rested on the shelf provided with the plane fluorescent lamp.
  • the abutting portion of the price card restricts the products at a location behind the riser flange of the shelf and prevents the products from moving forward beyond the abutting portion, so that the front surface side of the products is located behind the riser flange by a predetermined distance.
  • This arrangement in combination with the fluorescent lamp positioned more closely causes the front surface side of the products to be illuminated with even higher illuminance.

  • An AC power source is connected to the electrode lead wires through wiring (not shown) to effect discharge between the discharging electrodes 144 and 144.
  • This causes accelerated electrons 146 to collide with the mercury (Hg) or argon (Ar) molecules and to change the energy level from the normal state to the excited state.
  • the excited molecules or atoms radiate ultraviolet rays peculiar to the individual molecules when they restore their normal state.
  • the ultraviolet rays bump against the phosphors 143 and 143 and are discharged in the form of visible light rays through the surface of the sheet glass 142. This enables the surface of the plane fluorescent lamp 31 to provide a predetermined level of illuminance in, for example, a milky color.
  • the plane fluorescent lamp 31 measures, for example, 50 mm deep, 300 mm wide, and about 10 mm thick. A plurality of the plane fluorescent lamps 31 may be disposed side by side in a line, depending on a place where they are installed. The plane fluorescent lamp 31 may, however, take any size if the strength thereof is not important.
  • the plane fluorescent lamp 31 is thin, namely, about 10 mm thick, permitting itself to be installed in a much smaller space than a space used to be required for installing a conventional type of fluorescent lamp. Hence, the space in the display compartment 13 can be increased.
  • the plane fluorescent lamp 31 emits milky light rays from its surface, obviating the need for providing a separate shade on the front, with a resultant reduction in cost.
  • a card carrying characters or a shade in a desired color may be installed on the front surface of the plane fluorescent lamp 31 for ornamental purpose to improve product display sales effect, thereby promoting customers' appetite for buying the products.
  • the plane fluorescent lamp 31 is also advantageous in that it exhibits good low-temperature properties as compared with conventional fluorescent lamps, so that its illuminance is not affected even in a relatively low-temperature environment, such as in a low-temperature showcase.
  • the plane fluorescent lamp 31 is also advantageous from the safety viewpoint, because the surface of the plane fluorescent lamp 31 does not become hot, so that there will be no problem in that customers, employees, etc. get burns on their hands or fingers from accidental touch to the fluorescent lamp. Moreover, the plane fluorescent lamp 31 does not add to heat load, contributing to improved cooling efficiency. The plane fluorescent lamp 31 does not have a temperature difference between its ON mode and OFF mode, making it possible to prevent dews from being produced on its surface. This arrangement obviates the need for installing a heater as a heat generating member for preventing dews, as in a conventional art, thus allowing a reduction in cost.
  • the plane fluorescent lamp 31 has a markedly longer service life than that of a standard fluorescent lamp, requiring no frequent maintenance work, such as replacing old fluorescent lamps failing to properly stay ON.
  • the shelf 91a shaped like a box is formed by injection-molding a polystyrene (PS) resin, and has the riser flange 92a for restraining products from falling at its front, a semicircular protuberance 94a being formed on the front top portion of the riser flange 92a.

  • the locking portion 98a also has a curved recessed portion 100a located at a position associated with the protuberance 94a of the shelf 91a mentioned above.
  • the price card 96a is composed of a piece of paper or a resin sheet on which a price or a product name has been printed.
  • a member that is slightly longer in the longitudinal direction than the supporting portion 106a of the insertion portion 97a of the price rail 93a is prepared, and inserted in the insertion portion 97a of the price rail 93a. Then, the price rail 93a is inserted from above the shelf 91a.
  • the price card 96a is slightly longer than the supporting portion 106a of the insertion portion 97a; hence, the price card 96a can be removed by pulling it up while pushing the portion slightly extending upward beyond the supporting portion 106a from the back of the abutting portion 99a by a finger, and replaced by another desired price card 96a having a different product name or price printed thereon.

  • the cold air then moves up in the rear duct 41 and enters the top duct 51 through the communication apertures 42 and 53, and moves forward. Thereafter, the cold air is discharged from the discharge port 61 toward the front opening 12 of the display compartment 13.
  • the cold air discharged from the discharge port 61 moves toward the inlet 29 while forming an air curtain at the opening 12, and is suctioned into the inlet 29 by the suction force of the blower 19 by being guided by the plane fluorescent lamp 31.
  • a part of the air curtain is circulated in the display compartment 13 to cool the interior of the display compartment 13 to a predetermined temperature.
  • a part of the cold air leaving the cooler 18 enters the lower discharge duct 23, moves forward therein, and is discharged to the front of the longitudinal wall portion 6C from the lower discharge port 22.
  • the display portion 95a on the front surface of the price rail 93a is curved, so that the flow of the aforesaid air curtain formed at the opening 12 can smoothly moves toward the inlet 29 without being blocked.
  • the cooling effect on the low portion 6A of the display surface of the lowermost stage which is located farther from the discharge port 61 tends to deteriorate.
  • the cold air is directly supplied from the lower discharge port 22, thereby solving the deteriorated cooling effect problem.
  • the lower discharge port 22 is provided with the discharge guide 26, and the protuberance 27 is formed therebelow; hence, the discharge of the cold air from the lower discharge port 22 or the circulation of the cold air will not be interfered with by the product V on the low portion 6A.
  • Height L1 from the bottom surface, that is, the installation surface, of the unit base 3 of the showcase 1 to the upper surface of the top plate 8 is set to 700 mm to 750 mm (715 mm in this embodiment), and height L2 to the display surface of the lowermost stage (the low portion 6A) is set to a value within a range of 100 mm to 200 mm (149 mm in this embodiment).
  • Height L3 from the installation surface to the upper edge of the plane fluorescent lamp 31 is set to 200 mm to 210 mm (205 mm in this embodiment), and height L4 from the installation surface to the display surface of the middle stage (the high portion 6B) is set to a value within the range of 300 mm to 400 mm (304 mm in this embodiment).
  • height L5 from the installation surface to the display surface of the uppermost stage (the shelf 91) is set to a value within the range of 400 mm to 700 mm (489 mm in this embodiment), and height L6 from the installation surface to the front edge of the top plate 8 is set to a value within the range of 650 mm to 700 mm (668 mm in this embodiment).
  • Longitudinal dimension L7 of the showcase 1 is set to a value within the range of 450 mm to 550 mm (490 mm in this embodiment).
  • a typical height of the cash register counter C provided at a convenience store ranges from 800 mm to 1000 mm, and a typical depth thereof is about 550 mm. Therefore, the showcase 1 in accordance with the present invention can be stably installed on the cash register counter C, and is capable of displaying the product V while cooling the product V in the display compartment 13. This makes it possible to promote customers' appetite for buying the products V, such as bottled or canned beverages, that are preferably sold especially in the vicinity of the cash register counter C, thus contributing to increased sales.
  • the height from the floor to the display surface of the lowermost stage ranges from 900 mm to 1200 mm.
  • This range of height of the display surface of the lowermost stage (the low portion 6A) corresponds to the range of the height of the waists to chests of most customers, allowing the visibility of the product V on the lowermost stage to be improved and also enabling customers to easily take out the product V.
  • the height of the display surface of the middle stage (the high portion 6B) and the height of the display surface of the uppermost stage (the shelf 91, or the high portion 6B if the shelf 91 is not installed) from the installation surface range from 300 mm to 700 mm.
  • the height from the floor to the display surface of the uppermost stage (the shelf 91 or the high portion 6B) ranges from 1100 mm to 1700 mm.
  • This height range of the display surface of the uppermost stage approximately corresponds to the height range of customers' bellies to faces, leading to improved visibility of the product V on the uppermost stage and also enabling customers to easily take out the product V.
  • the machine chamber 14 is configured to have the lower front and the higher back by the stepped configuration of the adiabatic wall 4.
  • the display surface of the lowermost stage (the low portion 6A) can be set low, while allowing the bulky units, such as the compressor 63 and the condenser 64, to be installed at the back in the machine chamber 14.
  • the hot air coming out of the notches 3B flows along the outer surface of the outer plate 82 at the bottom of the side plate 7 to heat a portion in the vicinity of the inlet 29 that is apt to have dews, thereby preventing the dews.
  • the hot air flowing into the exhaust duct 86 rises therein and eventually moves out toward the outer surface of the outer plate 82 at the front through the exhaust ports 87 in the front surface, as shown in Fig. 10.
  • the top end of the exhaust duct 86 is closed by the top plate 8, so that the pressure (static pressure) at the upper portion of the exhaust duct 86 rises, and the volume of hot air flowing out increases in higher exhaust ports 87. Therefore, the hot air is preferentially supplied to the upper portion of the outer surface of the outer plate 82 which is near the discharge port 61 and where dews are most likely to appear, thus allowing the dew problem to be effectively solved.
  • the abutting portion 99a forming the upper edge of the display portion 95a of the price rail 93a is positioned above the riser flange 92a of the shelf 91a, causing the front surface of the product V to abut against the abutting portion 99a.
  • This means that the product is supported at above the riser flange 92a of the shelf 91a, minimizing the chance of the product falling off the shelf 91a. If the shelf 91a inclines downward toward the front, then even if the product V slips down on the shelf 91a and inclines forward, the product is pushed back by the abutting portion 99a.
  • the display portion 95a of the price rail 93a is curved and its bottom edge abuts against the bottom edge of the riser flange 92a; hence, even if the product V bumps against the abutting portion 99a with momentum, the deformation of the display portion 95a can be minimized, and the effect for preventing the product V from falling forward can be further enhanced.
  • the price card 96a is hardly exposed because it is inserted in the insertion portion 97a of the price rail 93a, and the upper edge portion of the price rail 93a covers the top of the price card 96a, the price card 96a is scarcely soiled by dust or the like. Even when the price card 96a is formed of such a material as paper or the like, the price card 96a will be able to survive an extended use.
  • FIG. 17 shows a second embodiment in accordance with the present invention.
  • a box-shaped shelf 91b is formed by injection molding by using a polystyrene (PS) resin.
